Your Answer: x10 AnswerIn an air bag safety test, two identical crash test dummies are placed in a vehicle equipped with air bags. The air bag in front of one of the dummies is disabled so that it does not function. The car is then crashed into a rigid barrier and sensors within each of the dummies record the forces acting on the dummies during the collision. A graph of the collision force on the dummies as a function of time is shown below. Force on Crash Test Dummies as a Function of Time Dummy I Force (kN) Dummy II Time (ms) The air bag in front of Dummy | is _. and the impulse experienced by Dummy I is the impulse experienced by Dummy II during the vehicle collision. O disabled; the same as O functioning; the same as O functioning; larger than O disabled; larger than Question 16 (1 point) Force on a Ball as a Function of Time FINI The net impulse delivered to the ball from t 0.0 to t = 6.0s is ab Ns.
